ANTISEPTIC FOOD-COOLER.

SPECIFICATION forming part of Letters Patent No. 651, 250, dated June 5, 1900.

Application filed February 19, 1900. SerialNo. 5,725. (No model.)

T all whom it Wuty concern:

Be it known that we, CHARLES H. HOW LAND-SHERMAN and ALAN M. BENNETT, citi- Zens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Antiseptic Food-Coolers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will to enable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to the preservation of articles of food, and has especial reference to means for preserving food in hot climates, by

the use of antiseptics to destroy microbes and other deleterious animal matter, and a cooling medium to maintain a low degree of temperature; and it consists in certain improvements in construction which will be fully dis- 2:) closed in the following specification and claims.

In the accompanying drawings, which form part of this'specification, Figure 1 represents a top plan View of our invention; Fig. 2, a

vertical longitudinal section; Fig. 3, an inverted plan with the retention plate removed; Fig. 4, a vertical longitudinal section of the cover for the chamber for a cooling medium; Fig. 5, an enlarged detail sectional view of c the cover for the food-cooler; Fig. 6, atop plan and a vertical sec iofi of the antiseptic-receptacle on an enlarged scale; and Fig. 7, a top plan view of the support for the antisepticreceptacle, also on an enlarged scale.

R Kerence being had to the drawings and he letters thereon, A indicates the body of /bur improved food-cooler, having a central chamberB to receive articles of food to be preserved, and is provided with a receptacle a to 0 receive an antiseptic, such as suitable chloride, well known, for the purpose of destroying microbes and other deleterious animal matter, and is supported upon a .U-shaped holder 12 with its open upper end near the up- 5 per end of the chamber B. The holder extends through the wall 0 of the chamber B and is secured by nuts 01 d, which engage one side of the wall, and collars c e, which engage the opposite side. The receptacle a is provided with a flange cl at its upper end, which rests upon the holder and prevents it falling through the loop 6' in the holder. The chamber B is provided with a cover O, formed of two pieces f g, provided with horizontal flanges f g, which rest upon each other, with a chamber h between the parts f g to receive a non-conductor of heatsuch as wool, felt, or suitable material hand the pieces are se cured together by bolts "5, which pass through the flanges f g and have a rabbet it around the lower flange g and a packing Z, of leather, paper,or other material,cemented to the lower side of the projecting part of flange f, as shown in Figs. 2'and 5. The lower flange g of the cover loosely enters the chamber B, allowing the packing Z of the flange f to form an air-tight joint around the upper edge of the food-chamber, and rests upon the wall Z) between the food-chamber and the coolingchamber.

D is an annular chamber surrounding the chamber 13 for containing a suitable refrig: erant--such as liquid air, liquid ammonia, or

ice--and is provided with a removable annu lar cover E, provided with a chamber con taining a non-cond uctor m and an annular retention-plate n for securing the non-conductor in the chamber. The plate 11 is secured by bolts 0, and on each edge of the cover is a rabbet p and a packing q, the part 1 of the cover entering the chamber D in the same manner as the corresponding parts of cover O enter chamber B and rests upon the walls I) c between the chambers.

The chambers B and D are separated by the vertical wall b" and both open at the upper end of the cooler, and the cover of either one can be removed without interfering with the other.

F is a chamber surrounding and separated from the chamber D by a vertical wall 0', extends underneath both chambers B and D, and on the under side of the bottom 3 of the chambers B and D are projecting ribs 25, which strengthen the bottom and form a support for the retention-plate, and said chamber F is packed with a non-conductor of heat a of the kind used in the cover O or any preferred kind, and the non-conductor is retained in the chamber by a retention-plate 41, secured by bolts 20, extending through the bottom of the chamber D and resting against the ribst and upon ledge 15'. This chamber F opens or is accessible from the bottom of the article and may be thoroughly packed with a nonconductorot' heat and the base-plate applied.

The chamber D is provided with a faucet G for drawing 01f any liquid that may accumulate therein.

The cooler is designed to be made, preferably, of stone or pottery ware, the chambers, their fixed walls, and the bottom of the chambers B and D being integral to avoid leakage, with the inside of the chambers B and D glazed, and the retention-plates n and v are designed to be made of sheet metal, with the lower surface of the former enameled to prevent corrosion,the preferred form of the cooler being elongated, as shown, for the purpose of accommodating like forms of plates or dishes containing food to be preserved.

The cooler, which is designed for convenient manufacture in all sizes, can be advantageously utilized for a large variety of hos pital and domestic uses, being readily portable and easily operated.

Having thus fully described our invention,

what we claim isl. A cooler having a chamber for articles to b. ooled provided with a receptacle for an antisep a cooling-chamber separated from and surroi "ding the food-chamber, a chamher around tln oolingehamber and extend ing under the foo and the cooling chamber, a non -conductor 0 ieat filling the latter chamber, a cover for te food-cooling cham-. ber resting upon the wall b ween said chamber and the cooling-chamber, ad a separate annular cover for the cooling-cl1amber resting upon the same wall and the wall t-ween said cooling-chamber and the chamber f thenon-conductor.

2. A cooler having a chamber for articles to be cooled, a surrounding chamber for a cooling medium, a chamber surrounding the latter chamber, all of said chambers being separated by fixed integral walls, and the latter chamber provided with a non-conducting material, a non-conductor of heat under all of said chambers, a cover for the center chamber and aseparate annular cover for the chamber containing the cooling medium.

3. A cooler having a chamber for articles to be cooled, a surrounding chamber for a cooling medium, accessible from the top of the cooler and provided with separate detachable covers, a chamber surrounding the latter chamber and accessible from the bottom of the cooler and all of said chambers being separated by fixed integral walls, and the latter chamber provided with a non-conducting material, a non-conducting material under all of said chambers, and a retention-plate in the bottom of the cooler.

4. A cooler having a chamber for articles to be cooled, a surrounding chamber for a cooling medium, separate detachable covers for said chambers provided with a non-conducting medium and resting upon the walls between said chambers, a chamber surrounding the latter chamber, and a chamber under all of said chambers, the concentric chambers being separated by fixed integral walls, and

the latter chamber provided with a non-con duc'tor of heat, and a retention-plate in the bottom of the cooler.

5. A cooler having a chamber for articles to be cooled, a concentric chamber for a cooling medium separated by a fixed integral wall, and a non-conductor of heat around the latter chamber and under both chambers, a retention-plate removable from the bottom of the cooler, and a removable cover made in two parts, provided with flanges by which the parts are secured together, separable horizontally and having a non-conductor of heat interposed between the two parts.

6. A cooler provided with a two-part cover having flanges by which the parts are detacha-bly secured together and separable horizontally, one of which flanges extends beyond the other and forms a rabbet around the lower flange, and a chamber between said parts provided with a non-conductor of heat.

7. A cooler provided with an annular cover having a chamber in its lower side provided with a non-conductor of heat and having rabets on both edges thereof extending around the ver,in combination with a cooling-chamher, a Y.at-non-conducting chamber, and a separablexstg ition-plate in the bottom of said chamber, saic ever resting upon the wall between the cooling' iamber and theheat-nonconducting chamber.
